- 摘要:
- 该研究以唐山市南堡盐场重盐碱地为例，采用基盘育苗、台田整地、客土穴移植树苗等措施，探讨滨海盐碱地基盘法造林技术。结果表明：基盘具有一定阻隔盐碱的作用，客土、草炭、蛭石和珍珠岩体积比以5：1：2：2的种基盘出苗率最高，且蛭石和珍珠岩组合占优势的基盘配方出苗率高于草炭占优势的基盘配方，基盘苗早期受外界环境的不利影响较大，不同配方的基盘对基盘苗的根系发育和地上部生长量的影响大小还有待研究。台田的排盐阻盐效果以南北两条“十”字型（炉渣）的最好，炉渣隔离层比建筑垃圾隔离层的排盐阻盐效果明显。客土穴具有较好的阻盐效果，大部分移植树苗成活。研究结果可为滨海盐碱地造林提供一定技术支持。
- Abstract:
- Taking a badly seashore saline land in the city of Tangshan as an example, adopting some measures, such as sowing by seed-bases to breed seedlings, building stair-fields, transplanting seedlings in carrying soil columns etc, a new technology of seed-base for afforesting was developed in seashore saline land. The results showed that the seed-bases had a certain function of anti-salt. Vermiculite and pearlite had a better effect compared with peat in the rate of emergence, and the seed-base that was made by carrying soil, peat, vermiculite and pearlite in the volume ratio of 5:1:2:2 had the highest rate of emergence. The seed-base seedlings were vulnerable to the external environment when they were young, and how much the influence of different prescriptions of the seed-bases for the seed-base seedlings’ roots development and later growth was still to be further studied. The isolation layer of slag was better than the one of construction waste in anti-salt, and the stair-field with a slag layer in the shape of two stripes from south to north and one strip from east to west had the best effect on anti-salt. The carrying soil columns could prevent transplanting seedlings from the harmful effects of salt, which made most of transplanting seedlings survive. The results could provide a certain technical support for afforesting in Seashore Saline Land.
